High-strength wear-resistant TPU composite material production line and production process thereof

Abstract

The invention belongs to the technical field of TPU composite material production, and particularly relates to a high-strength wear-resistant TPU composite material production line and a production process thereof. The high-strength wear-resistant TPU composite material production line involves a mixing device used for mixing materials, a coating device used for coating the materials, a vulcanizing device used for vulcanizing treatment, a laminating device used for laminating treatment and a stripping device used for stripping treatment, wherein the coating device comprises a bottom frame. Twoindependent coating containing cavities are formed in a coating pool through a partition plate and can contain coatings of different materials, material pumping pumps communicating with the interiorsof the coating containing cavities are arranged on the outer sides of the two coating containing cavities, the input ends of the material pumping pumps communicate with the coating containing cavities, the output ends of the material pumping pumps are arranged on a secondary coating roller through material conveying pipes, different coatings can be conveyed to the secondary coating roller, when the materials are conveyed to a main coating roller and the secondary coating roller through a tensioning roller, the double faces of the materials can be coated at the same time, different coatings orthe same coatings can be coated, the application range is wide, and the coating efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of TPU composite material production, and in particular relates to a high-strength wear-resistant TPU composite material production line and a production process thereof. Background technique [0002] TPU material is the abbreviation of Thermoplastic Urethane, and the Chinese name is thermoplastic polyurethane elastomer. TPU is a polymer material formed by the reaction and polymerization of diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with macromolecular polyols and low molecular polyols (chain extenders). TPU has Excellent high tension, high tensile strength, toughness and aging resistance characteristics, is a mature environmental protection material. At present, TPU has been widely used in medical and health care, electronic appliances, industry and sports, etc. It has the characteristics of high strength, good toughness, wear resistance, cold resistance...

AI Technical Summary

Problems solved by technology

[0003] In the production process of the current TPU composite material, various materials need to be coated back and forth on the TPU base material to form a composite material. China Patent Network has proposed a TPU film stretching and flattening device on the laminating machine (public number is CN106142799A ), the patent uses a hammer-proof rotating roller and an arc-shaped bending roller to stretch the TPU film from the middle to both sides, so that all the folds of the corroded TPU film can be stretched out, avoiding the situation of artificial stretching causing crushing and uneven stretching However, in the production process, the TPU base film cloth needs to be repeatedly coated on both sides, the process is more complicated, and the multiple stretch coating increases the damage of the TPU base film during the coating and stretching process. Probability, increase the production of bad materials, reduce production efficiency and production quality
